    I have 2 goldfishes of size about 4 inches(without tail) in 25 gallon aquarium. Can i add 2 Koi fishes of same or small size with them?

    Do you mean if you get a large pond? Koi get huge, and so do most goldfish.

    Koi get 2 feet long or bigger, common goldfish get 8-12” if not bigger.

    You can but you will need a bigger tank or a pond.
